that was very easy... didn't pick it up at first but once I read the clue I knew instantly what was going on...

I have no idea here! Enlighten me please?

What game? Craps?

That was easy..

the game is called "buzz" and what you do is a group of people sit around in a circle, and one of them starts by saying "1". The next person (clockwise) says "2" and they keep going until they come across a number divisible by 7 or contains a 7: in which case they say "buzz". Anyone who screws up by unnecessarily saying buzz or not saying it when they should, they are out and everyone continues until only one person is left. He/she is the winner.

by the way, they start counting over each time somebody is out.

back to 1.

Very easy.

You are my saviour! 'Q

Why should they start counting over each time somebody is out? I think they should continue, because people are more likely to make mistakes in larger numbers.

thats dumb. what game?

Yeah this was really easy for me because I play it at school for Maths every week. It's a fun game and I usually win. Good riddle, I guess, although too easy.

I saw it! I just couldn't say it into words? lol

I got the multiplication of 7 quickly, took me a little more studying to get the 7 as second digit.

good one!

good one!

Never heard of the game, would never have figured this out. Quite a challenge. Thanks for posting.

The hint was worthless but I still figured it out.

If you follow the sequence of the sequence of a number ending in 7 and the number following it be divisable by 7 should the 7 and 8 numbers in the sequence be 37 and 42, NOT 35 AND 37, therefore making the correct answer to the braingle 47 and 49.

EXPLIANATION

first 7,14

second 17,21

third 27,28

fourth should be 37, 42

and not 35 and 37

therefore fifth in sequence 47, 49

Kasie, you are changing the original sequence, which would negate the whole teaser.

Kasiecom, why skip 35? It is divisible by 7.

NICE!!!

I KINDA got it, but got the numbers wrong. I keep telling you I'm "numerically challenged!" I might as well delete the quiz when it has number in it!

very easy

The number 7 isn't the only one used, it's just the toughest for younger kids. Any (single-digit) number can be used.

A variation of the game is Bizz Buzz, where two numbers, say 7 & 4, are used. Players say "Bizz" on the sevens, "Buzz" on the fours, and "Bizz Buzz" on the numbers divisible 4 & 7 or have 4 & 7 in them.

Very easy. I enjoyed it only because the unknown numbers have some symbolical value to me.

Se7en

Made me feel less math challenged-thank you!

I got it, too, and was happy for the same reason as you, Maggie!

Happy MAY and good health, every one!

For those of us who never played that game or ever heard of it, the puzzle was totally random. The hint only acted as a misdirection for the same reason - you had to have played that game to get it.

I've never heard of the game, but I did figure it out - sort of. I started with "7" and every other number added 10 (7-17-27, etc); the interspersed numbers were multiples of 7 - except when I got to the last 2 numbers (35, and 37) they were backwards - I thought that was a typo and turned them around - so I still got the right answer!

good quiz!!

good quiz!!

guys when I saw the answer I thought that it is wrong .. someone should light me ... which is right answer (42,49)"it is mine" or (42,47)"the written one" ????
